DUPLEX PUMP STATION CONTROLLER
ENERGY EFFICIENCY
OPERATION
Energy and maintenance expenses for a typical pumping
system can add up to be more than 65% of the total life
cycle cost. Therefore, energy efficiency is a critical factor
when investing in new equipment or simply retrofitting existing control systems. With the Eco Smart Station® control
system featuring the Energy View® controller, up to 30% energy savings is achievable.
During high in-flow operation (peak hours) it
is more efficient to operate in proportionalintegral-derivative (PID) mode than cycling
the pump ON and OFF. kW Logix® Software
recognizes high in-flow conditions and automatically switches the operation mode from
ECO mode to PID mode. During PID operation, the pump speed is controlled to match
the incoming flow and maintain a constant
wet well level. When the in-flow returns to
normal, the operation returns to cycle based
(ECO mode) operation automatically.
ENERGY SAVINGS
The Affinity Laws define the relationship between pump
speed (n) and power (P):
P2 = P1 (n2/n1)3
Motor speed (n) in RPM can be controlled with the use of
Variable Frequency Drives (VFDs):
n = (120 x Hz)/Poles
The Energy View® controller with the kW Logix® Software
uses an “Efficiency Auto-Tune” algorithm that searches for
the pump speed (Hz) that will consume the least amount
of energy per gallons of liquid pumped (W/GPM). The flow
(GPM) is calculated from the level changes, tank dimensions,
fill and discharge times. A flow meter is not needed.
Motor Speed vs. Energy Savings
The pump motor power (W) is monitored by the VFDs and
transmitted to the controller. No power meters are required.
The auto-tun program takes into account the reduction in flow
and head characteristics of the pump resulting from speed
reductions to determine the Best Efficiency Frequency (BEF).
When the Best Efficiency Frequency (BEF) is found, the
pumps will operate at this speed during every cycle. This
mode of operation (ECO mode) is very efficient during low
and normal in-flow to the station.
